Thanks for reply harald sir.
Is there any way to convert all the edges to bidirectional? Or any other
solution,if you may suggest?
I have modify the code as following :
> def get_EdgeId_From_vertex(prenode,nextnode):
# Retrive Edge Id from Graph by giving Previous Node and Next Node
for x in graph.getNodes():
if(str(int(x.getID()) - 1) == str(prenode)):
#print 'Out Going Edge of :' + str(x.getID()) + ' Are ' +
> str(x.getOutgoing())
for edge in x.getOutgoing():
#check if Next node of this edge is nextnode??
if(int(str(edge.getToNode().getID()))-1 == nextnode):
return str(edge.getID())
> for edge in x.getIncoming():
#check if Next node of this edge is nextnode??
if(int(str(edge.getFromNode().getID()))-1 == nextnode):
return str(edge.getID())
> But this gives error :
*traci.exceptions.TraCIException: Vehicle 'vehicle0' has no valid route. No
connection between edge '8' and edge '11'.*
